Replace an old bell.
We check the new model against the existing wiring, transformer and chime, then fit it and test it.
DOORBELL & INTERCOM INSTALLATION / MELBOURNE At the front door.
Doorbells & intercoms.
Rough-in to fit-out.
Doorbells, chimes and intercoms, installed start to finish.
Cabling, power, mounting and testing in one job.
01 / A SMALL DETAIL AT THE ENTRANCE
Know the product.
Plan the whole job.
Doorbells and intercoms vary: battery models, wired chimes and intercom systems each have their own power and cabling needs. Existing bell wiring is not automatically suitable for a replacement.
Voltra Electrical installs doorbells and intercoms across Melbourne, from rough-in to fit-out. The rough-in is the cabling we run while walls and ceilings are still open during a build or renovation. The fit-out is mounting the door station and inside unit, connecting them and testing. We also replace and add doorbells and intercoms in finished homes.

We rough in the cabling before the walls are closed, then come back to fit off the door station and inside unit.

02 / THE WORK, CONSIDERED
A tidy installation.
Starting behind the button.
CONSIDERED / FROM START TO FINISH
The supply matters.
So does the position.
We check the manufacturer’s requirements and the available installation route. Doorbell voltage, transformers and chimes must be assessed as a system.
We confirm the product’s power and cabling needs before agreeing the installation. Share the model and chime details where available so the whole job can be planned together.
Plan your doorbell or intercom03 / KNOW YOUR SETUP
Before you order.
Check the details.
Send the model number and a photo of the entrance to help establish what is involved.
- Power requirements
- Different models use batteries, a transformer or other specified supplies. Do not connect a doorbell based only on its appearance.
- Wiring & chimes
- Existing wiring and a mechanical or electronic chime may not suit the chosen product.
- Plan the rough-in early
- Building or renovating? Tell us before the plastering so the cable to the door and the inside unit goes in while the walls are open.
- Position & weather
- Consider the entrance, mounting height and exposure to weather before choosing the position.

05 / BEFORE WE GET STARTED
Good questions.
Clear answers.
Can you install a doorbell I have bought?
Send the exact model first. We assess product suitability, wiring and the supported installation scope before confirming the booking.
Can existing bell wiring be reused?
Possibly. The wiring, supply and chime must meet the new product’s requirements; an existing bell does not prove compatibility.
Will it work with my current chime?
That depends on the doorbell and chime combination. Provide both model details so the manufacturer’s compatibility information can be checked.
Do you install intercoms?
Yes, start to finish: the cabling, the power supply, the door station and the inside unit. Send the model so we can check its requirements.
Can you rough in a doorbell or intercom on a new build?
Yes. We run the cabling while the walls and ceilings are open, then fit off the door station and inside unit once the walls are finished.
Can you add a new doorbell where there is none?
Yes. We plan a cable route from a suitable supply or transformer to the door, with a chime where you will hear it.
Can you install at a rental or apartment entrance?
Relevant owner or owners-corporation permission may be needed. Confirm permission and shared-property limitations before arranging work.
